Review Summary

Reviewed the x86-64 assembly implementation of `curve25519_x25519base` in `aws-lc/third_party/s2n-bignum/s2n-bignum-imported/x86_att/curve25519/curve25519_x25519base.S`. It appears to be a standalone constant-time X25519/Edwards25519 field-and-point arithmetic routine with embedded read-only precomputed tables; I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators.
